A fuzzy approach for the selection of non-traditional sheet metal cutting processes
Cortés Sáenz, David; Gordillo Castillo, Nelly; Riba Romeva, Carles; Lloveras Macià, Joaquín
This work presents a methodology for the selection and comparison of non-traditional sheet metal cutting processes as a new structure of selection by means of an expert system. The model is generated from a knowledge base acquired from diverse experts, and the use of fuzzy logic techniques. With a simple input of the parameters of a piece, the system offers the most appropriate cutting options (based on the requirements of the piece) allowing a non-expert user selecting the most appropriate process with emphasis on a predefined priority: finish, cost or time. The selection process consists of four base algorithms that measure the attributes of each process as a dependent indicator of the other processes, that is, a pre-selection that considers (1) the process capability to cut a material-thickness relation, (2) the speed that can be achieved with this relation, (3) the inherent complexity of the piece to be cut, and (4) the process tolerance. Results of experiments under three different approaches prove that the expert system here presented accurately prioritizes the most convenient cutting processes.

El presente artículo explora sectores que identifican la innovación en empresas farmacéuticas de España. Para ello se consideran firmas nacionales y filiales extranjeras establecidas en territorio nacional. El análisis realizado comprende el periodo de 2009 al 2011 para una población N=200 empresas afiliadas en ese momento a Farmaindustria y al Plan Profarma. El trabajo consistió en una búsqueda de información útil en las páginas web de las empresas farmacéuticas establecidas en España que pudieran describir de forma estática el perfil innovador del sector farmacéutico español a través del análisis estadístico descriptivo. De esta forma, se crea un cimiento para la documentación de los resultados en una base de datos con el propósito de obtener un panorama con determinación sobre el comportamiento del sector farmacéutico español, así como posibles tendencias.
El alto contenido de aportación literaria sobre el sector farmacéutico, se expresa de forma globalizada a nivel nacional e internacional, desestimando datos e información que pudieran ofrecer señales de amenaza u oportunidad respecto al corto periodo de tiempo, ya que a su vez son equiparables a otros años puesto que la industria farmacéutica española se constituye por empresas de origen extranjero (50.5%) y de capital nacional (49.5%). De éstas últimas las pymes son las protagonistas de las pequeñas innovaciones de las firmas establecidas en Madrid y Barcelona principalmente.

The Effect of volumetric (3D) tactile symbols within inclusive tactile maps
Gual Ortí, Jaume; Puyuelo Cazorla, Marina; Lloveras Macià, Joaquín
Point, linear and areal elements, which are two-dimensional and of a graphic nature, are the morphological elements employed when designing tactile maps and symbols for visually impaired users.
However, beyond the two-dimensional domain, there is a fourth group of elements - volumetric elements - which mapmakers do not take sufficiently into account when it comes to designing tactile maps and symbols.
This study analyses the effect of including volumetric, or 3D, symbols within a tactile map. In order to do so, the researchers compared two tactile maps. One of them uses only two-dimensional elements and is produced using thermoforming, one of the most popular systems in this field, while the other includes volumetric symbols, thus highlighting the possibilities opened up by 3D printing, a new area of production.
The results of the study show that including 3D symbols improves the efficiency and autonomous use of these products.

Domestic oven heated by a concentrating solar collector
Lloveras Macià, Joaquín
A project to power a domestic oven by solar energy was developed. The focal axis of a cylindrical parabolic reflector usually reaches temperatures of up to 250ºC. A heat transfer fluid carries this heat to the heat exchanger in the oven. Current domestic ovens are generally electric and can reach 250ºC with a power of 2-3 kW.
The installation is composed of pumps, valves, thermally insulated pipes, exchanger, etc. These elements transfer the heat collected by the solar collector to the oven in the house. If the installation has an accumulator tank with thermal insulation, the high temperature liquid makes it possible to use the oven at any time.
Unlike current domestic solar ovens, this technology can reach the same temperature and power as an electric oven, and be used indoors at any time.
Additionally, this system could be used for sanitary hot water purposes and radiating floors. In these cases, the high temperature is degraded mixing with cold water.

Water self-sufficiency with separate treatment of household rainwater and greywater
Lloveras Macià, Joaquín; García Blanch, Elisa; García Gisbert, Anna; Planas Gisbert, María; Rodríguez Farre, Ariadna
This paper is based on an academic work conducted by a group of students of the Engineering Project
course within the Chemical Engineering Degree at the Engineering School of Barcelona. The objective of
the exercise was to design a rainwater harvesting and greywater recycling system for a detached house
and calculate the number of people that could be self-sufficient. Local rainfall, roof area for collecting
rainwater and daily water consumption per inhabitant were considered. The effective amount of rainwater
and purified greywater was also obtained.
In this design, the rainwater is filtered, stored and preserved in a tank, and disinfected with UV light. A
small quantity can be made drinkable. The greywater is filtered, treated in a biological reactor,
flocculated, sedimented and finally disinfected with UV light.

The economic model based on the consumption of fossil fuels, mainly oil,
historically has fostered a growth of civilization, but it has not taken into account
the consequences for the environment, now beginning to be analyzed due to
the different impacts observed. It is necessary a clean energy production
worldwide.
In the current economic crisis, especially in southern Europe, one of the
challenges of change is the energy model, both to improve environmental
impacts and to improve the balance of payments, without losing
competitiveness. The first conditions that must have the new energy model
2
promoted by the European Union (EU) are the savings, efficiency and clean
energy production, discussed in this article.
Renewable energies are inexhaustible and widely distributed. Its use in a higher
percentage than today, will impact less on the environment, improve the
balance of payments, and create new jobs.

Three-dimensional tactile symbols produced by 3D Printing: Improving the process of memorizing a tactile map key
Gual Ortí, Jaume; Puyuelo, Marina; Lloveras Macià, Joaquín
The aim of this article is to determine whether the process of memorizing a tactile map key, or legend, can be improved by including three-dimensional (3D) symbols produced by means of 3D Printing. The method used in this study involved asking a group of 20 volunteers with different profiles to memorize eight tactile symbols from two keys, each of which had different characteristics: Key 2 included 3D tactile symbols and Key 1 had only two-dimensional (2D) tactile symbols. Results show statistically significant differences between the two keys. Use of Key 2 yielded a 48.72% reduction in the number of errors compared to Key 1 (N = 20, p-value = .014). These data show that combining 3D with flat relief symbols (2D) improves the process of memorizing a tactile key because the 3D attributes can be distinguished from the 2D features by touch. For practitioners, this article provides data about the possibilities of 3D Printing applied to tactile maps, keys, and symbols.
